Abstract

The invention relates to a dual-clutch transmission with a magnetic torque adjustor. The magnetic torque adjustor mainly comprises a first smooth motor, a second smooth motor and an energy storage capacitor, wherein the first smooth motor is connected with a driving disc of the dual-clutch transmission, the second smooth motor is connected with an output shaft of the dual-clutch transmission, rotating speed of the driving disc and the rotating speed of the clutch are dynamically synchronized through driving force and regenerated braking force provided by the two smooth motors, the rotating speed difference is stabled within an extremely small error range to achieve the effect of smooth gear shifting, an expensive power battery pack and a high-power large-size motor are not needed, the inherent defect of jerking gear shifting of the dual-clutch transmission is overcome, and the dual-clutch transmission with the magnetic torque adjustor is particularly suitable for improving a fuel vehicle provided with the dual-clutch transmission.

Description

【Technical field】 [0001] The invention relates to a dual-clutch transmission for vehicles, in particular to a dual-clutch transmission with a magnetic torque regulator and a control method suitable for improving internal combustion engine vehicles. 【Background technique】 [0002] Automatic transmissions include AT (Simpson Transmission), CVT (Continuously Variable Transmission), and DCT (Dual Clutch Transmission). AT and CVT are equipped with hydraulic torque converters. DCT basically cancels the hydraulic torque converter, making the transmission more direct and fuel efficient The economy is even better. DCT is divided into dry type and wet type. The specific names have different names in different automobile manufacturers, including DSG, PDK, PowerShift, etc. DCT has high transmission efficiency and small size, but its shift smoothness and durability have always been criticized by consumers, especially when decelerating and accelerating at low speeds below 3rd gear, it is...
